Photoshop: Please drop the Deactivation feature

Please drop the deactivation requirement of an existing copy before allowing activation of that copy on a new system, even with a valid s/n, matching email, and Adobe account.

I rebuild Windows or upgrade hard drives or computers a few times a year and Photoshop is the only program I have that requires me to not only enter a s/n and activate online when installing, but unregister when uninstalling, deleting or reinstalling too; or if I forget that, making me contact support to prove I'm not a thief.

If you can't make it as simple as LightRoom or MS Office, I'd suggest just activating it on the most recent install hardware and automatically deactivating any other existing copies that phone home after that. Or just have us provide login credentials or answer security questions during install.

At a minimum, allow us to selectively deactivate licenses through adobe.com without jumping through hoops with live support, for times when the old copy is unavailable (formatted, dead machine, etc.).
